India’s commercial and industrial renewable capacity is projected to surge from 32 gigawatts (GW) in 2025 to potentially 100 GW by 2032, with energy storage system installations expected to increase more than tenfold to around 31 gigawatt‑hours, as per a recent report. The growth is attributed to corporate decarbonisation objectives, escalating grid tariffs, and a growing demand for energy resilience, supported by state‑level regulatory advancements.
The report, prepared by India Energy Storage Alliance and Customised Energy Solutions, will be unveiled during India Energy Storage Week (IESW) 2026 scheduled from July 8-10 in New Delhi. The event anticipates participation from over 200 exhibitors and 10,000 industry leaders, providing a platform for policy discussions, technical exchanges, and showcasing innovations in the clean energy sector.
Senior officials from various ministries, including Heavy Industries, Mines, Power, Electronics, and Environment, will collaborate with state representatives and regulatory bodies at IESW 2026 for open discussions. The focus will be on addressing policy challenges, state-level reforms, and industry requirements to expedite India’s transition towards clean energy.
“Our new research indicates that India’s C&I energy storage market is not only expanding but accelerating towards a new phase. With progressive state policies and growing corporate demand, storage is evolving into a strategic tool for resilience and decarbonization, rather than just a backup solution,” stated Debmalya Sen, President of IESA.
The report also highlights Maharashtra’s fresh renewable energy and storage policy, mandating storage for all new renewable projects exceeding 100 kilowatts. Additionally, distribution companies are required to source 10 per cent of their electricity from storage by FY 2035–36. States like Gujarat, Karnataka, Tamil Nadu, and Rajasthan are facilitating swift adoption through cost-reflective banking, settlement policies, and exemptions on transmission charges.
Industrial facilities are anticipated to lead in storage adoption, constituting more than half of all ESS installations, while sectors like data centers and critical infrastructure such as hospitals, metro and railway stations, and airports are expected to witness rapid growth.
